I know how important it is to ensure that your Constant Contact email is delivered. This is something that I would like to look further into for you. Please send an email to social_support(at)constantcontact(dot)com with the name of the campaign in question, your Constant Contact username and a reference to this post. At that time we will take a look at the email in question and see if we can determine what may be happening.
Please let us know if you have additional questions. Thanks and have a great day!
